Recommendations?

The Royal servant...

kirai de isasete is omegaverse, uke already has a child but then they have another one later on

Wait I didn't mean to recommend that one... There is this other manga where they have a alpha x omega pairing and a beta x beta pairing and the beta was the Omega's butler... can't remember the name though
